Spatial data infrastructures model for developing countries: A case study of Nigeria
This research explores the basics of SDI, and investigates the National SDI of different countries. Further, the research analyses SDI implementation in developing country with specific reference to the National Geospatial Data Infrastructure (NGDI) of Nigeria. The research assesses the status and the milestones of NGDI implementation using key SDI components as assessment variables. These components were grouped into four classes: Policy and Legal Issues, Technical, Funding and People. A questionnaire survey via email was conducted on the stakeholders and users of geoinformation in Nigeria. From the analysis, the NGDI has an advantage of having a national policy backing its implementation and the establishment of the coordinating body. However, the lack of SDI directive and funding are major hurdles in the implementation of the NGDI making it lack behind most of the selected case study countries in other key components. Nigeria is also found to be applying a Mixed Model of NSDI implementation as both product model and process model are evident in the NGDI. In the real sense of access network and data sharing, NGDI is yet to be operational, though the project is going on.

Lagos State GIS Progress
The increasing awareness in Lagos of the use of geographic information for planning and decision making led to the 'Lagos State Digital Mapping and GIS Project.' The project was proposed by the Office of the Surveyor-General and later placed in the hands of a Technical Committee set up by His Excellency, Mr Babatunde Raji Fashola (SAN) and Chaired by the Honourable Commissioner for Science and Technology, Dr Kadri Obafemi Hamzat. The project is divided into seven modules:
- Acquisition of Digital Aerial Imageries and Establishment of Geodetic Control;
- Establishment of Geoid and Active Global Positioning System (GPS) and Reference Station with (Continuous Operating Reference Station (CORS);
- Digital Mapping, Digital Terrain Model (DTM) and Orthophoto Map;
- Enterprise GIS;
- Bathymetry;
- Provision of ICT Infrastructure, Education and Training; and
- Public Enlightenment and Stakeholders meetings.
The mapping products that will be delivered under this Project will be at the scale of 1:500 for metropolitan Lagos and 1:1,000 for rural areas. The other products include: Orthophoto (1:2,000), contour lines (1:500 – urban and 1:1,000 in the rural area), Digital Elevation Model and Digital Terrain Model.
Currently, the project is in various stages of completion viz:
MODULE 1
Acquisition of imageries is 100% completed while the image processing of the Aerial Photo is on-going. However the lidar data acquisition is presently on-going.
MODULE 2
The Continuous Operating Reference Station been constructed is almost completed.
MODULE 3
Once the Digital Aerial imageries (module 1) is completed the end result will bring to the completion of the Digital Mapping, Digital Terrain Model and Orthophoto Map (module 3)
MODULE 4
The enterprise GIS is on-going
MODULE 5
Bathymetry which is the data acquisition of all the Lagos Lagoon and creek has been completed while the processing of the data is presently on-going.
MODULE 6
The provision of ICT infrastructures such as the ICT Laboratory, V- SAT is ready and been currently utilized by the end –users while the education of the participants in the projects drawn from MDA’s is a continuous exercise and is on-going.
MODULE 7
Awareness and public enlightenment campaign is going on to sensitise the general public and stakeholders in the industry about the numerous benefits the project would bring to the development of various sectors of the economy such as Land and water, Resources ,Transport Population Census, Education, Health, Security, Budget and Planning, Tourism, Agriculture, Mineral Resources, Environment, Local Government, Sport, Infrastructure.
In order to achieve the above, two stakeholder’s Conferences has been held to further deliberate on the extent of work done, the way forward for the Lagos State Digital Mapping and Geographic Information System. More stakeholders meetings and Conferences shall be organised as the need arises to further sensitise the general public and stakeholders in the industry.
The Lagos State Government in order to promote greater awareness and public access to standard and coordinated geospatial data production, management and dissemination by all sectored institutions, ministries, departments, agencies and the privates sector is establishing a Geospatial Data Service Centre (GDSC).
The Lagos Enterprise GIS database will be backed by a policy to eliminate problems experienced by Geo-information producers and users in the State today. A Technical Committee has put in place modalities to produce the State Geo-Information policy. The GDSC is domiciled in the Office of the Surveyour–General.
National Emergency Management Agency (NEMA) sets up GIS. In an effort to make efficient its work in managing disaster across the country, the National Emergency Management Agency (NEMA) has established a functional Geographic Information System (GIS) lab for Early Warning for disaster responses. The Director General of the Agency, AVM Muhammad Audu-Bida, said at the first 2009 Ministerial Press Briefing in collaboration with Federal Ministry of Information and Communications, the lab is one of the significant facilities of the agency for its disaster risk reduction programme; it collects spatial data on disasters, analyses and prepares useful information that can help in aid responses to disaster. The DG said that disaster management in Nigeria mainly focuses on humanitarian relief supplies, with huge funds expended anually. Among other things the agency adopted for coordinating disaster management, according to him included Mission Control Centre (MCC), which is a computer based satellite technology that uses what he called the "COSPAS-SARSAT hi-tech system". This system, he said is designed to pick distress alerts and location data to assist in Search and Rescue Operation (SRO), by using satellite and ground facilities to detect and locate the signals of distress beacons operating on 406MHz.
The Nigeria Conservation Foundation has included the use of GIS as a tool for its school visits to the Lekki Conservation Center.ArcView 3.3 was used to visualize the National Bounbary, State Boundaries, National Parks and Strict Nature reserves in Nigeria.This promotes environmental education process by showing students the location of the National Parks, Ramsar Sites, Strict Nature Reserves and the vegetation types in each Reserves. The process also includes the use of Multimedia GIS through the hotlinking fuction to attach Animal Pictures,Vegetation Scenes perculiar to each National Park. The result of these was seen as the GIS Tool was able to answer location based question posed by the Students who were keened as knowing the location of some national Parks, What animals do we have where, the name of the protected areas, etc.
